In addition to boiler prices, the consumption of fuel 1 ton boiler is also a common consideration for most customers.Then,how to calculate boiler fuel consumption.Fortunately,there is a same calculation method Whether it is natural gas boiler consumption, gas consumption of 2 tons biogas boiler, or 10MW natural gas consumption amount of gas boiler.

calculations of 1tph boiler gas consumption

Taking a 1 ton natural gas boiler as an example, so you can take this as reference and calculate fuel required for any capacity of Boiler for any fuel.

Following parameters are required to calculate fuel consumption to boiler.

Boiler Capacity - 1000 kg/hr

Steam Pressure - 10.5 kg/cm2(g)

Steam Temperature - 185.5 Deg c (Saturated Steam)

Enthalpy of Saturated Steam - 664.2 kcal/kg

Enthalpy of Feed water - 105 kcal/kg

Fuel - natural gas

Calorific value(GCV) - 2272 kcal/kg- (It is the amount of heat liberated in Kcal by the complete combustion of 1 kg of fuel)

Boiler Efficiency - 95 % based on ZBG natural gas boiler

So,when you get these parameters,you can calculate 1tph boiler gas consumption by following calculations.

Fuel Required = Heat Input required (kcal/hr.) / Calorific Value of that fuel (kcal/kg)

Heat Input required (kcal/hr.)= (Boiler Capacity x (Steam Enthalpy - Feed water Enthalpy))/(Boiler Efficiency)

For above parameters:Heat Input required = 1000 x (664.2 -105)/0.95 = 588631.6 kcal/hr

Fuel Required = 588631.6/2272 = 259kg/hr

Fuel Required for 1 TPH Boiler is 259kg/hr.That means by burning 259kg/hr of of gas, you can generate 1000 kg/hr saturated steam at 10.5 kg/cm2(g) pressure.
